SPECIFICATION forming part of Letters Patent N 0. 701,972, dated June 10, 1902. Application filed September 23, 1901. serial No. 76,272- (No model.)

To all whmn it may concern:

Be it known that I, THOMAS S. WARNER, a citizen of the United States, and a resident of Frankfortfin the county of Marshall and State of Kansas, have invented new and useful Improvements in Cultivators, of which the following is a specification.

My invention relates to that class of cultivators wherein the cultivating appliances may be lifted from the ground without caus-.

ing the front end of the tongue to pull .upward; and my object is to produce a machine of this character wherein the ground may be efficiently cultivated with each passage of the machine, so as to obviate the necessity of using a second cultivator to follow and loosen up the ground behind the leading oneand outward of the furrows made by the'disks side elevation of the gang at the left-hand end of the seat-plank, the tongue and the shovel-shanks being broken away. Fig. 3 is a sectional view taken on line a b ofFig. 2., looking in the plane of the ring and omitting the disks,shovels,and their supports, the seatplank being broken away. Fig. 4 is a plan of one of the gangs, omitting the seat-p1ank.'

, I prefer to employ two gangs of disks and shovels, as shown in Fig. 1, these constituting a double-row cultivator. Each gang is provided with a tongue 3, secured to a ring 4. As the tongues arianorihallyhigher at their front ends when in use than at their opposite ends, blocks 5 are secured between the rear por-' tions of rings 4 and thetong'ues for holding the rings approximatelyhorizontal. The two gangs are connected by a seat-plank 6, supported near its ends by the rings 4 and retained thereon by rods 7, connected to clips 8, mounted slidably upon said rings. The

gangs are thus prevented from tipping laterally. A longitudinal slot 9 is out near one end of the plank 6 to receive a pin or stud 10, secured rigidly to the tongue 3. A similar pin or stud 11, secured to the other tongue 3, extends through a hole in the plank near its opposite end. The slot 9 permits the righthand gang to adjust itself to rows of Varying widths, as the pin 10 is movable in said slot.

12 designates the drivers seat, secured'to the plank 6.

In Figs. 2, 3, and 4 only one gang of'cultivating devices is shown, as the constructions of the two gangs shown in Fig. l are identical. Each gang is mounted on two wheels 13, as shown in said Figs. 2, 3, and 4, and comprises two shovels 14 and two disks 15.

The

lower disk-arms 16 are secured by eyebolts 17 to castings 18,which are secured with clips 19 upon a transverse rocker-bar 21, mounted in collars 22 in bearings 22, connected by depending arms. 23 to the lower face of the ring 4 at opposite points. The wheel-arms 24 are also secured with clips 25'to the rocker-bar 21 between the castings 18 at an. angle of about ninety'degrees with the disk-arms 16.

- Each shovel-beam 26 is bolted to a casting 27,

and said castings 27 are pivotally secured to castings 18, respectively, at 28 and further secured thereto by bolts 29, said bolts 29 being adapted to engage any one of a series of holes in castings 27 for the purpose of efiecting vertical adjustment of the shovels with relation to the disks, as will be understood by reference to Fig. 2. Formed at or near the lower ends of the wheel-arms 24, respectively, are two forwardly-extending perforated lugs or eyes 31, to which are connected the lower ends of two rods 32, the upper ends of which are connected, respectively, to cranks 33, rigidly secured on a shaft 34, mounted in bearings on a casting 36, bolted to thetongue.

A hand-lever 37 is secured on shaft-Mand is. provided with a latch for engaging'a notched segment 38. By moving lever 37forward--=- t'. a, to the left inFig. 2- -the rods 32 are caused to push the wheel-arms 24 backward, thereby raising the disks and shovels higher.

Reverse or back movement of lever 37 permits the wheels 13 to run forward, and the disks and shovels are correspondingly lowered. It will be readily understood that the backward shifting of the wheels 13 when the shovels are being raised throws the center of gravity of the whole machine forward, thereby largely counteracting the upward tendency of the front portion of the tongue caused by the weight of the shovels, disks, and their supports. As shown in Figs. 3 and athe cranks 33 are farther apart than the wheelarms 24:, and the rods 32 therefore converge downwardly to connect with said arms. The castings 18 and the wheel-arms 24: are adjustable laterally along and upon the rocker-bar 21 and are shown in the drawings as disposed upon said bar in a most advantageous position for cultivating the field on the first passage of the machine thereover-that is, with the wheels 13 and the cultivating appliances as near to the center of the machine as possible. Before cultivating the ground the second time the castings 18 and the wheel-arms 2a are moved farther apart on rocker-bar 2'1, and the rods 32 will then be more nearly vertical or may be farther apart at their lower ends than the cranks 33.

I have found that by associating the disks and shovels together in the manner indicatednamely, with the shovels to the rear and outward of the disks-it is unnecessary to employ a second cultivator to follow up the leading one, because the shovels loosen up the earth between the rows, and thus perform the function which said second cultivator has performed heretofore. As a result an economy of time and labor is effected.

From the above description it will be apparent that I have produced a machine embodying the features of advantage enumerated as desirable in the statement of invention and which by the use of the rings 4 and sliding guides mounted thereon and holding the seat-plank in position makes it possible for the machine to turn with greater freedom than in machines of this type in which the plank has only a very limited pivotal movement.

Having now fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is--- 1. In a cultivator,a suitable carrying-frame, atongue therefor, a ring rigid with the tongue, and beams provided with cultivating appliances at one end and pivotally supported at the other from said ring so as to be capable of vertical movement independent of the ring.

2. A double-row cultivator, having a seatplank pivotally connected to each cultivating member of the machine; a ring forming a part of each member and a support for one end of the seat-plank; and means for holding the plank across the faces of said rings without impeding its pivotal movement thereon.

3. Adouble-row cultivator, comprising two tongues, a ring secured to each tongue, a gang of cultivating devices secured to each ring, a seat-plank connecting and supported by said rings, and devices for holding the seat-plank in contact with said rings, substantially as described.

4..
